The paper examines seasonal exometabolite patterns in the oligotrophic ocean, linking microbial functions to DOM dynamics and showing DOM composition is more stable than microbial community structure.

The paper describes 81 new SAR11 isolate genomes and identifies 29 monophyletic ecotypes within the Pelagibacterales, providing a classification system correlated with ecology and evolution.

This study identifies 79 VOCs affected by viral infection in Gephyrocapsa huxleyi, revealing a six-fold increase in VOC production during lysis and a previously unrecognized diversity of compounds.

The paper identifies VOC-specialist bacteria in diatom cultures and shows their impact on carbon cycling and diatom productivity.

The paper analyzes SAR202 bacterial genomes to show paralog expansions correlate with metabolic specialization and niche adaptation across ocean depths and regions.
